[PATCH v3 4/5] Makefile: the "cscope" target always creates a "cscope.out"

["Ævar Arnfjörð Bjarmason" <avarab@gmail.com>]

In the preceding commit the "cscope" target was changed to be a phony
alias for the "cscope.out" target.

The cscope target was added in a2a9150bf06 (makefile: Add a cscope
target, 2007-10-06), and has always referred to cscope* instead of to
cscope.out.

As far as I can tell this ambiguity was never needed. The
"-fcscope.out" (note, no whitespace) argument is enabled by default,
but let's provide it explicitly for good measure.
